Nebius signs as anchor tenant for Volt's €7B Rotterdam AI gigafactory
October 12, 2026
Landing one tenant is what lets a speculative data-center plan start courting banks and regulators.
- Nebius signed a letter of intent to become the first tenant of Volt's planned AI gigafactory on Rotterdam's Maasvlakte, taking up to 200MW of the project's first phase, valued at roughly €7 billion ($7.8B).
- Volt, founded in 2025 by CEO Han de Groot, is developing a campus eventually sized up to 600-800MW, with power sourced from North Sea offshore wind delivered via energy partner Eneco.
- The first phase covers two 100MW buildings; of the €7B, about €2.5B funds construction and infrastructure while €4.5B covers chips and hardware, including 100,000 AI chips earmarked for Nebius alone.
- The agreement is a non-binding letter of intent, not a signed lease; Nebius can walk away if the project is delayed, and first capacity isn't expected until late 2029 or early 2030.
- The Dutch government declined to back Volt's bid for an EU-subsidized AI gigafactory program, choosing instead to fund a smaller facility in Groningen, leaving Volt to raise financing privately.
- Nebius has been striking major compute deals globally, including a $17.4 billion agreement with Microsoft, a $27 billion contract with Meta, and a $2 billion investment from Nvidia.
- A named anchor tenant is the credibility signal gigawatt-scale data center developers need to unlock bank and investor financing — without one, a site is just a permit application.
